Electrode assembly manufacturing device and electrode assembly manufacturing method

A manufacturing apparatus of an electrode assembly, comprising:

• a first machine vision provided on a driving-direction front end of a first electrode from a winding core, the first machine vision being configured to measure a first non-overlap width between a first width-direction end portion of the first electrode and a first width-direction end portion of a first separator;
• a second machine vision provided on a driving-direction front end of a second electrode from the winding core, the second machine vision being configured to measure a second non-overlap width between a first width-direction end portion of a second electrode and a first width-direction end portion of a second separator;
• a controller configured to:
• collect vision data obtained from the first machine vision and the second machine vision;
• set a non-overlap width between the first separator and the second separator to 0 through vision data;
• compute a third non-overlap width between the first width-direction end portion of the first electrode and the first width-direction end portion of the second electrode;
• and
• judge a meandering defect with the computed third non-overlap width;
• a data processing unit configured to accumulate and process defect judgment data through machine learning;
• and
• an input unit configured to automatically input a meandering reference value based on the data processed by the data processing unit.
